Katherine Jackson, mother of the late singer Michael Jackson, is resigning as legal guardian of the "King of Pop's" youngest son, Blanket.

The court documents starting the process of the change of guardianship said Katherine is “no longer needed to fulfill the duties” that were needed in 2012, when Katherine and TJ, Blanket's cousin, were appointed co-guardians of Michael’s three children.

Katherine’s resignation will leave TJ as the sole guardian of Blanket.

Given her age, Katherine, who is now 87, said she "feels that TJ is able to assume all necessary responsibilities of the guardianship" for Blanket, the court documents say.

The documents have been filed, but the family must now wait for a judge to make a decision about the request.
